WHEEL-HUB.

Specification of Letters Patent.

Patented May 8, 1906.

To all whom it may concern.-

Be it known that I, OLIVER LUNDIN, a citizen of the United States, residing at Ollie, in the county of Keokuk and State of Iowa, have invented a new and useful Wheel-Hub, of which the following is a specification.

This invention relates to wheel-hubs, and has for its object to improve the construction and increase the efficiency of devices of this character.

With these and other objects in View, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment ofthe invention capable of carrying the same into practical operation, it being understood that various changes in the form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention within the scope of the appended claims.

In the drawings, Figure 1 is a longitudinal sectional elevation of the improved device applied to an axle-journal of uniform diameter throughout. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional detail illustrating the modifications required to adapt the device to a tapered journal.

The improved device may be applied to any size of axle-spindle, either straight or tapered, bymaking slight and immaterial modifications in one of the parts, and for the purpose of illustration the device is shown in Fig. 1 applied to an axle-journal of equal size throughout, and in Fig. 3 are shown the changes required to adapt the device to a tapered journal.

The improved device comprises a thimble 10 of larger diameter than the journal or spindle 11 and with a flange 12 at one end bearing upon the spindle next to the collar 18, usually employed upon axles between the spindle and the body or stock of the axle, and also bearing over the collar, as shown. The thimble 10 extends longitudinally to the spindle 10 for a portion of the length of the latter, and mounted upon the spindle and extending its whole length, except the small portion covered by the flange 12 of the thimble 10, is an axle-box 14, the inner end of the box thus extending between the spindle 11 and thimble 10. Bearing over the outer end of the box 14 is another thimble 15, having an inwardlythreaded flange 16 engaging the threaded end 17 of the spindle and also with an outwardly-extending flange 18. The threaded flange 16 is spaced from the outer end of the thimble 15, whereby a recess 19 is formed beyond the threaded end 17 of the spindle, and formed upon the inner Walls of the recess are lugs 20 for receiving a suitable implement for rotating the thimble in placing in position or removing from the spindle.

The box 14 is provided with intermediately disposed flanges 21 2 spaced apart a distance equal to the width of the spokes of the wheel measured longitudinally to the axle, the flange 22 being fast to the box or integral therewith, while the flange 21 is slidable on the box. The stationary flange 22 is also provided with a shoulder 23 on the side next the axle-collar 13.

The hub of the wheel is formed in two parts, with sleeves 24 25, bearing, respectively, over the thimbles 10 and 15 and with relatively large flanges 26 27 for bearing upon opposite sides of the spokes, (represented at 28.) The spokes are secured in place by rivets 29, passing through both flanges and between the spokes, the latter being recessed where the rivets pass, as shown. The rear end of the sleeve 24: bears over shoulder 39 on the flange 12 of the thimble 10 and also bears against the rear end of the same flange, while the outer end of the sleeve 25 bears over the flange 18 of the thimble 15 and extends a short distance beyond the same to form a sand band or guard to the outer end of the thimble and the threaded end 17 of the spindle. The inner end of the sleeve 24 is provided with an annular recess to receive the flange 22 of the box 14., while the inner end of the sleeve 25 is provided with a similar recess to'receive the slidable flange 21. The sleeve 24 thus bears only at the ends or upon the shoulder 39 of the flange 12 and upon the flange 22, while the sleeve 25 also bears only at the ends or upon the flanges 18 and 21, as shown. The space between the flanges 18 and 21 and the sleeve 25 and thimble 15 is preferably filled.

tured and in which the wearing partsare reduced to a minimum. It will also be noted that the bearings come only at the ends of the two hub members 24 27 and 26, thus producing a structure in which the wear is imparted principally upon the inner and outer surfaces of members 10 and 15.

Having thus described the invention, What is claimed is 1. A wheel-hub comprising a box for bearing upon the axle-spindle, a thimble extending over the inner portion of said box and provided with a terminal flange for bearing against the collar of the spindle, said flange having an annular shoulder forming an external bearing, a thimble extending over the outer portion of said boxzand having a threaded flange engaging the threaded end of the spindle and with an outwardly-extending flange at the outer end forming an annular bearing, two:sleeves extending over said thimbles and respectively bearing upon the shoulder and upon the annular bearing on the same, said sleeves having laterally-extending flanges at their inner ends bearing against opposite sides of the spokes, and means for coupling the spokes and said sleeve-flanges.

2. A wheel-hub comprising a box for bearing upon the axle-spindle and with spaced flanges between the ends of the same, a thimble extending over the inner portion of said box and provided with a terminal flange for bearing against the collar of the spindle, said flange having an annular shoulder and forming an external bearing, a thimble extending over the outer portion of said box and having a threaded flange engaging the threaded end of the spindle and with an outwardly-extending flange at the outer end forming an annular bearing, two sleeves extending over said thimbles and respectively bearing upon the shoulder and upon the annular bearing thereon and provided with annular recesses in their inner ends for bearing upon said intermediate box-flanges, flanges extending laterally from the inner ends of said sleeves and bearing upon opposite sides of the spokes, and means for connecting said sleeve-flanges and-spokes.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
